The last wild Atlantic salmon that return to U.S. rivers have had their most productive year in more than a decade, raising hopes they may be weathering myriad ecological threats.
PORTLAND, Maine (AP) — The last wild Atlantic salmon that return to U.S. rivers have had their most productive year in more than a decade, raising hopes they may be weathering myriad ecological threats.
The fish are protected by the Endangered Species Act, and sometimes only a few hundred of them return from the ocean to the rivers in a year.
The greater survival of the salmon could be evidence that conservation measures to protect them are paying off, said Sean Ledwin, director of the Maine Department of Marine Resources sea-run fish programs.
Commercial fisheries for wild Atlantic salmon in the U.S. closed decades ago due to overfishing and pollution.
The count of salmon at the Milford Dam in the Penobscot River has been over 1,000 in four of the last five years, Maine data show.
“It’s going to take a commitment from everybody in the world to reduce emissions, and try to negate the most severe implications of climate change,” Crabbe said.
